Simplifying Rational Expressions
posted by mike on .
Can someone PLEASE solve these for me
1.4x12/4x
2.d+7/d^249
3.t^225/t^2+t20
4.2x^2+6x+4/4x^212x16
5.6y/y^22y24
You need to use parentheses to clarify the menaing of those expressions. For example, if you mean
(4x12)/4x instead of 4x  (12/4x), then the answer is
4(x3)/x = 4[1  (3/x)]
Similarly,
(d+7)/(d^249)= (d+7)/[(d+7)(d7)]
= 1/(d7)
Use similar approach with the others. Dactor the numerators and denominatores, and cancel out common factors.
(4x12)/4x = 4(x3)/4x = (x3)/x

12x1
